“…Recently, Meijboom and colleagues 17 have demonstrated that coronary ostial aneurysms are a common finding in patients with Marfan syndrome after elective aortic root surgery, even when the button technique is used. On the other hand, owing to the limited data on patient surveillance by means of imaging techniques, the true incidence of anastomotic complications after the modified Bentall procedure may be underestimated 18 . Long‐term results of our patients do not exist.…”

“…The normal diameter of native coronary vessels can be underestimated in post-mortem and conventional invasive angiographic studies [11-14]. These studies usually assess only the mid-portion of the proximal segment of the coronary vessels rather than the ostium (the aorto-coronary junction), and report diameters of 2–5 mm for the RCA and 4–7 mm for the LMA.…”

BackgroundDuring the modified Bentall surgery (aortic root replacement), a cuff of native aorta is implanted, together with the coronary ostium, into the aortic graft. Multi-detector computed tomography (MDCT) imaging can accurately assess the coronary ostial anastomosis site post-surgery. In this study, we assessed the feasibility of imaging the coronary ostial anastomosis site using transthoracic echocardiography (TTE).MethodsPatients (n = 14, mean age 65 ± 12 years, 79% males) with previous Bentall surgery underwent TTE study, with MDCT (64-slice) as the reference standard. TTE used conventional and novel acoustic windows to interrogate the coronary ostia.ResultsAll coronary ostia (n = 28) were well-visualized with MDCT. The optimum TTE acoustic window for visualizing the coronary ostia was a superiorly positioned parasternal short-axis view with the probe tilted towards the left shoulder, medially angulated for the right coronary artery ostia (RCAos) and laterally angulated for the left main coronary artery (LMAos). In this off-axis position, 10 (71%) LMAos and 13 (93%) RCAos could be visualized. In the conventional parasternal views, only 5 (36%) RCAos and no LMAos could be visualized. TTE underestimated the diameter of the LMAos (10.0 ± 2.4 mm TTE vs. 13.4 ± 2.7 mm MDCT, p = 0.007), but was similar to MDCT for the RCAos (9.8 ± 3.1 mm TTE vs. 11.1 ± 3.2 mm MDCT, p = 0.10).ConclusionsWe report a novel TTE acoustic window to image the coronary ostia of post-Bentall surgery patients. Although TTE underestimates the left coronary ostium size, recognition of the ostial dilation with TTE appears feasible in most patients. Those that cannot be imaged will require alternative imaging modality such as MDCT.

“…The present study showed that whilst conventional TTE failed to adequately assessed the coronary ostia of these patients, an alternative novel TTE acoustic window was able to visualize most of the coronary ostia, thus providing a potentially suitable alternative noninvasive imaging tool to monitor the coronary ostial dilation long-term. The normal diameter of native coronary vessels can be underestimated in post-mortem and conventional invasive angiographic studies [11][12][13][14]. These studies usually assess only the mid-portion of the proximal segment of the coronary vessels rather than the ostium (the aortocoronary junction), and report diameters of 2-5 mm for the RCA and 4-7 mm for the LMA.…”
